Long story short — my warlock 9/dragonslayer 3 with practiced invoker feat started summoning tier 1 undead instead of tier 2 after drinking a heroism potion (it likely caused her to lose one caster level). The rest helped though, and I tested it several times — heroism potion triggers this bug. Then the server has reset and this bug became permanent, meaning I have to ask for character rebuild now, and when I do I have no guarantees this won't repeat again!

upd: I rcred my character into warlock 12, but I'm still having this issue, sometimes I summon tier 2 undeads though, this bug turns on/off randomly

Another bug appeared! Since the latest update, Flee the Scene doesn't apply haste buff anymore. Instead, it applies 3 separate buffs (movement speed bonus, attack bonus and armor bonus). It still gives additional attack, yes, but that's still awful. For example, it doesn't nullify slow debuff anymore, and a slowed character under the effect of new bugged flee the scene still remains slowed.

Not a bug, working as intended to keep the extra attack when you reapply it early. As far as no longer removing Slow I think we can fix that part.

Another warlock bug. When logging in as a hellfire warlock the hellfire shield has a "persistant aura" even when disabled which causes you to be fined and banned from the FAI. This has happened to me twice now.

Should also be sorted next update.

Slow/haste like effects should also cancel each other again.

Regarding DR issues I don't think there's a clean fix at all (nothing seems wrong script wise so it's the engine who handles the different DR poorly) therefore I'll simply deactivate it if you're a warlock.

Invocation Hellspawned Grace doesnt take the changes to shapechanging into account, like bonus AC with Shield,Armor,NA,deflection or weapon EB/properties.

Overall the Hellspawned Grace shape was far worse than my stats without shapechanging.

Also as i shapechanged back to my human form there was still an Improved Invisibility on me as spell effect which i had to remove to enter the FAI court. Tough i couldnt see effects of invisibility on me.

Wasnt able to reproduce this effect a 2nd time, but didnt try further after the 2nd attempt.
